1) A rule of thumb has been developed over the years to help simplify this process. To select the correct capacitance value, start with 30 to 50μF/kW and adjust the value as required, while measuring motor performance. We also can use this basic formula to calculate capacitor sizing : 2) Determine the voltage rating for capacitor.
